Question

Transcribed Image Text:**Data**
- **Complete the data table.**
| **Table 3. Mannitol Salt Agar** | | |
|:-------------------------------:|:--------:|:--------:|
| **Bacterium** | **Result** |
| *Staphylococcus aureus* | ______ / ______ |
Explanation:
The image presents a table labeled "Table 3. Mannitol Salt Agar" with two columns. The first column is titled "Bacterium" and lists "*Staphylococcus aureus*". The second column is titled "Result", and it is blank, requiring students to complete it. This table is part of the data collection section for an educational purpose, likely involving an experiment using Mannitol Salt Agar to observe the results. Students must fill in the results based on their observations or experimental data.

Transcribed Image Text:### Data
#### Description
The image displays two petri dishes used in a microbial growth experiment. Both dishes are labeled "AZM."
1. **Left Petri Dish (Negative Control | Uninoculated)**
- **Appearance**: Clear red medium without any visible growth.
- **Purpose**: Serves as a control to show the medium's appearance without microbial inoculation.
2. **Right Petri Dish (Staphylococcus aureus Inoculated)**
- **Appearance**: The medium shows a distinct change in color from red to yellow, indicating microbial activity.
- **Purpose**: Demonstrates the growth and activity of Staphylococcus aureus, which can cause a visible change in the medium.
#### Interpretation
- **Negative Control (Uninoculated)**
- No changes in the medium, confirming that the red color is the baseline state of the uninoculated agar.
- **Staphylococcus aureus (Inoculated)**
- **Color Change**: The medium transition from red to yellow indicates metabolic activity and the possible production of acidic compounds by Staphylococcus aureus.
- **Growth Pattern**: The yellow region suggests areas of bacterial growth, while the red area indicates unaffected sections.
#### Conclusion
The data shown here reveals the comparative effects of inoculation with Staphylococcus aureus against an uninoculated control. The distinct color changes provide visual evidence of bacterial growth and activity, serving as a useful tool for studying microbial behavior in a laboratory setting.
